摘要	A high efficient and compact power train system which is capable of achieving energy saving and overload protection is required in electric vehicles (EV). This paper aims to present a novel design of a driving motor integrated with magnetic gears for EV applications. A permanent magnet type of magnetic gear-motor with two air gaps is developed, and a finite-element analysis software tool is employed to simulate the magnetic field of the proposed design where the output performance, i.e. the investigated simulation results, such as the torque curve and rotational speed of the ring with iron pole-pieces versus time respectively are presented. A 3 kW magnetic gear-motor is proposed for the application of electric golf carts for its unique features of compact size, concentric configuration, high driving torque and maintenance free.
